Bilateral Agreement – Russia/FAA
4
•Interstate Aviation Committee Aviation Registry (AR) and Federal
Aviation Authority of Russia (FAAR)Bilateral Airworthiness
Agreement signed in 1998
•Each agency considers certifications/findings as valid without
further finding The AR will accept FAA Airworthiness Approval Tags on parts only when the
FAA certifies that each part(s) conforms to AR approved design data
Is marked in accordance with approved procedures
Meets all additional requirements of the AR, as notified
Parts must have an 8130-3 tag referencing document for approved design
data
Direction of the PMA Discussion
• All discussion on the legal basis has ended
• All mention of safety issues have ceased
• Commercial aspects dominant – Individual customer specific
– OEM’s very active on restricting use of parts/data
– Lessor/financier education is key
• Smaller PMA supplier absorbed/partnering
• Significant focus on PM aspect of parts
• Revision D of 8110.42 in signature phase
• PMA approvals heading more to a risk based culture – Issue by FAA of the streamlined process policy
5
FAA Direction
• Separation of approval basis? – Production
– Engineering
– Installation
• Focus on supply chain – Who/what/how
– Frozen processes
– Management of sub-tier
– Flow down of requirements
– Lessons Learned
– Selection/de-selection of suppliers
• Less push for ODA – Operator confusion
• Harmonization of Critical Part definition – Aligns with FAA/EASA TIP

Where Can You Use FAA-PMA Parts?
Types of parts for which FAA-PMAs exist: Gears (CSD/IDG, ATS, APU, etc.)
Shafts (various components / accessories)
Bearings (rod ends, ball, roller, needle, spherical, tapered wheel, etc)
Bushings (bronze, teflon lined, flanged, etc.)
Filters (Oil, air, water, fuel)
Seals (o-rings, gearbox, various components / accessories)
Impellers, Turbine Wheels, etc. (various components / accessories)
Compressor Blades
Turbine Blades
HPT Shrouds
Electrical (switches, lights, sensors, LVDT etc)
Interiors/passenger accomodations
Galley products
Structures
Hardware (nuts, bolts, washers etc)
Landing gear
Avionics
Harnesses and cables
Ball screw actuators
Eligibility
“Crack down” on data sources
No blanket statements allowed
Data sources scrutiny

How do PMAs save airlines money?
Piece Part Price
• Every PMA company will use the standard verbiage –
40% or better
• Higher usage = bigger savings
• Incentive programs
• Cost avoidance based on historical stocking
• Reliability Improvements
• Options on parts
10
PMA parts are generally as reliable or more reliable than OEM
parts. Why?
1. PMA developers have the benefit of understanding the OEM’s
shortcomings
2. PMA developers often have newer materials, manufacturing
methods and hold tighter tolerances due to the re-engineering
process
3. Generally PMA developers avoid major problem areas that ADs
or major service bulletins have been written against
Reliability

Leverage
The influence you have
to negotiate yourself a better deal
Lease Holder Opinion
• Will allow - no critical/no-gas path PMA
• What’s in it for me?
• Ask and we can discuss
• Negotiate the use up front/early in the contract
• Financial institute????????
• Make your mind up
– Standardize use of PMA
– Decide what your policy is
13
New Services
• More active bundling of services
– PM of solutions
• PBH offering
– Emphasis on reliability of parts
• PMA supplier cooperation
• Input to maintenance cost drivers
• PMA/OEM packages
• Owner Operator Produced Parts
• New aircraft – what can you do for me?
14
OPERATIONAL Rules
• Deviation to CCLDC granted for PMA parts
– SFAR 88
– 737NG/757 Fuel Pump Parts
• Airworthiness Directive granted
– Landing Gear door hinge fitting AMOC for 737
• Use of TSO
– Cargo net approvals
15
Conclusion
• Every facet of aviation is using PMA
• PMA solutions available across a wide range of products
• PMA parts deliver significant savings via
– Direct part savings
– Reliability improvments
– Leverage in contract negotiations
• PMA parts are safe, reliable and a competitive
business advantage
